12) Set DDRAM Address (RE = 0)
Set DDRAM address to AC.
This instruction makes DDRAM data available from MPU.
In 1-line display mode (N = 0, NW = 0), DDRAM address is from "00H" to "5FH".
In 2-line display mode (N = 1, NW = 0), DDRAM address in the 1st line is from "00H" to "2FH",
and DDRAM address in the 2nd line is from "40H" to "6FH".
In 4-line display mode (NW = 1), DDRAM address is from "00H" to "13H" in the 1st line, from
"20H" to "37H" in the 2nd line, from "40H" to "57H" in the 3rd line and from "60H" to "77H"
in the 4th line.
13) Set Scroll Quantity (RE = 1)
Setting SQ5 to SQ0, horizontal scroll quantity can be controlled in dot units. (Refer to Table 9).
In this case of KS0078 can show hidden areas of DDRAM by executing smooth scroll
from 1 to 48 dots.
